java - 游戏打不开，黑屏

Question

我正在尝试 MrSnakey 游戏。当我运行它时，它没有给我任何错误。但是，模拟器在启动时显示黑屏。你们不知道如何解决吗？ 解决此问题所需的有关我的项目的任何信息，请告诉我，我会在此处发布。

首先是 list 文件

   <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.zardtechnologies.androidgames.mrsnakey"
    android:versionCode="1"
    android:versionName="1.0" >

    <application
        androidicon="@drawable/icon"
        android:debuggable="true"
        android:label="Mr. Snakey" >
        <activity
            android:name=".MrSnakeyActivity"
            android:configChanges="keyboard|keyboardHidden|orientation"
            android:label="Mr. Snakey"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <uses-sdk
        android:minSdkVersion="3"
        android:targetSdkVersion="12" />

</manifest>

其次是 MrSnakeyActivity

    package com.zardtechnologies.androidgames.mrsnakey;

import com.zardtechnologies.framework.Screen;
import com.zardtechnologies.framework.impl.AndroidGame;

public class MrSnakeyActivity extends AndroidGame {
    public Screen getStartScreen() {
        return new LoadingScreen(this);
    }
}

第三个是从 MrSnakeyActivity 链接的 AndroidGame Activity

package com.zardtechnologies.androidgames.mrsnakey;  
import android.app.Activity;
import android.content.Context;
import android.content.res.Configuration;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.os.Bundle;
import android.os.PowerManager;
import android.os.PowerManager.WakeLock;
import android.view.Window;
import android.view.WindowManager;

import com.zardtechnologies.framework.Audio;
import com.zardtechnologies.framework.FileIO;
import com.zardtechnologies.framework.Game;
import com.zardtechnologies.framework.Graphics;
import com.zardtechnologies.framework.Input;
import com.zardtechnologies.framework.Screen;

public abstract class AndroidGame extends Activity implements Game {
    AndroidFastRenderView renderView;
    Graphics graphics;
    Audio audio;
    Input input;
    FileIO fileIO;
    Screen screen;
    WakeLock wakeLock;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        boolean isLandscape = getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE;
        int frameBufferWidth = isLandscape ? 480 : 320;
        int frameBufferHeight = isLandscape ? 320 : 480;
        Bitmap frameBuffer = Bitmap.createBitmap(frameBufferWidth,
                frameBufferHeight, Config.RGB_565);

        float scaleX = (float) frameBufferWidth
                / getWindowManager().getDefaultDisplay().getWidth();
        float scaleY = (float) frameBufferHeight
                / getWindowManager().getDefaultDisplay().getHeight();

        renderView = new AndroidFastRenderView(this, frameBuffer);
        graphics = new AndroidGraphics(getAssets(), frameBuffer);
        fileIO = new AndroidFileIO(getAssets());
        audio = new AndroidAudio(this);
        input = new AndroidInput(this, renderView, scaleX, scaleY);
        screen = getStartScreen();
        setContentView(renderView);

        PowerManager powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
        wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, "GLGame");
    }

    @Override
    public void onResume() {
        super.onResume();
        wakeLock.acquire();
        screen.resume();
        renderView.resume();
    }

    @Override
    public void onPause() {
        super.onPause();
        wakeLock.release();
        renderView.pause();
        screen.pause();

        if (isFinishing())
            screen.dispose();
    }

    public Input getInput() {
        return input;
    }

    public FileIO getFileIO() {
        return fileIO;
    }

    public Graphics getGraphics() {
        return graphics;
    }

    public Audio getAudio() {
        return audio;
    }

    public void setScreen(Screen screen) {
        if (screen == null)
            throw new IllegalArgumentException("Screen must not be null");

        this.screen.pause();
        this.screen.dispose();
        screen.resume();
        screen.update(0);
        this.screen = screen;
    }

    public Screen getCurrentScreen() {
        return screen;
    }
}

我不知道需要什么更多信息，因为我不知道是什么导致我的应用程序显示为黑屏。 哦，是的，控制台日志:

没有错误。我认为该应用程序运行良好，只是它无法让我进入游戏。请帮我解决黑屏问题。如果你们需要更多信息，请告诉我，我会在这里发布。谢谢

您没有在任何地方加载布局文件。你需要调用 AndroidGame 中的setContentView(R.layout.main)。假设您的布局文件名为 main.xml
